| Abstract: |
| For the miniature and integration of positioning navigation and timing system, an integration solution of Micro-PNT system was proposed, which is an effective solution for micro air vehicle under GNSS denial environment. MEMS inertial instruments，chip-scale atomic clock，micro-processor，power chip and other chips were integrated based on rigid-flexible integration processing and Layout optimization technology. The integration frame and software flow were presented in detail. Designing was validated through system production. Problems of the integration for micromation were proposed through analyzing the integration form. Finally, microsystem integration frame of micro-PNT was proposed which was based on key parts and 3D microsystem integration processing in the future. |
